HENRY GASEBOLT, OF SAN FRANCISCO, CALIFORNIA.

GRIPE-OPERATING DEVICE FOR CABLE-WAYS.

SPECIFICATION forming part of Letters Patent No. 245,785, dated August 16, 1881.

Application filed March 17,1881. (No model.)

To all whom it may concern:

Be it known that I, HENRY CASEBOLT, of San Francisco, in the State of California, have invented certain Improvements in Mechanism for Operating the Gripin g Device of Cars Propelled by EndlessWire Ways; and I hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a longitudinal sectional view through a car having the gripe-operating mechanism attached. Fig. 2 is a sectional view on the line 00 x of Fig. 1. Fig. 3 is a top view of the operating-lever. Fig. 4 is an enlarged view of the lower end of the supporting-pipe and contained rod.

Heretofore in endless-oable-way systems the cars have been successfully operated only by coupling them to a separate vehicle having little or no spring or yield, and known among cable-road operatives as a dummy. This was necessitated because the gripe, if attached to the floor of a car resting on springs, was seriously aifected by the vibration of the springs sustaining the loaded car. The comfort of the passengers rendered the springs necessary, and, as they could not be dispensed with, the

gripe had to be attached to the dummy, as aforesaid, and to this dummy was coupled the car for containing the passengers.

The object of my inventioh is to avoid the necessity of using the dummy or separate truck for the gripe, and to attach the gripe-operatin g device directly to the passen ger-carryin g car 5 and my invention consists in mounting the gripe directly upon a frame-work attached to the car-axles and sustaining the fulcrum of the lever independently of the body of the car, whereby the vertical movement of the car-body due to the elasticity of the springs is notcommunicated to the gripe or cable.

In order that those skilled in the art may make and use. my invention, 1 will proceed to describe the manner in which I have carried it out.

In the said drawings, A shows the section of a car the axles of which carry two longitud inal angle-iron bars, 0 O, by means of boxes at 01. These bars support the loose bars L through the medium of staples I), which hold the griping device, as fully described and claimed in the patent issued to me February 15, 1881, and No. 237,813. Four feet, h h, support above the gripe (shown in dotted lines) a casting, H, having a central opening,into which is screwed a heavy pipe, F-say two inches in diameterwhich passes through a box, E, in the bottom of the car and up through an opening, e, in the roof, and havingscrewed upon the upper end a head, N, from which rise two parallel rack-bars, S S, (see Figs. 1 and 3,) between which lies alever, D, havingin its head a slot, 15, in which bears an anti-friction roller, n, journaled on a stirrup at the upper end of a rod, R, which passes down through pipe F, and is attached at its lower end to the moving jaw of the gripe. On each side of the center the segmental rack-bars have semicircular depressions dd, to serve as bearings for the fulcrum of the lever, consisting of lugs d on a line with the slot t. The lever is provided with a double pawl, 19, to engage the teeth of the rack-bar in whichever direction the lever is operated, the position of the man operating it changing with the direction of the travel of the car. The length of pipe F is such that the extreme vertical movement of the car upon its springs will not in any manner affect it. A small circular fender, I, is attached to pipe F above the roof, to prevent any rain or other objectionable matter from passingiuto the car through the opening surrounding the pipe.

It will be seen that I have provided a supporting device for the gripe and a fulcrum or bearing through which to operate it, connected only with the axles of the car and entirely independent of the car-body and its supports upon the boxes, and consequently the vertical movement of the car is not transmitted to the gripe or cable.

Rubber buffer-springs ttare placed on rods connected with the gripe-supports L, so that when the gripe seizes the cable there will be an elastic resistance to overcome the inertia of the car. The pipe is so much larger than rod R that the rod can move with the vibration 2. Thepipe F, extending through the car, of the gripe on its supports L L.
